I know it's a bit late but this could be done for kingy till the end of the season. To the tune of wild thing (would need a big drum for this one, anyone got one?)

Matt king
You make the wire sing
Your tries make everything groovy!
Matt king I think I love u
But I wanna see u score!!!
C'mon and thrill me!

Not sure how this ends but are a good bit of drumming and a final matt king would fit in somewhere. Could always replace matt king with Atkins for next year!

Ooooooooooooooooh

Atkins is a Wire, centre or the Wing
Used to bang Chanelle, now he play's with King
50 yards at Wembley, was such an Awesome sight
Almost unstoppable, he makes the rest look e.

Oooooooooooh

the repeat.

Tune of "oh my darling"

Got no history, got no history, Is Wigans favourite song,
Wish we'd thought of one as clever, where the hell did we go wrong
Build an empire, Build an empire. Put Moran up on the top
Put the Wire in the middle and we'll buy the bloody lot

WE ARE THE WIREMEN?

This might be a little more rousing, although nothing hits the heart more than the wiremen song sung by all! To the tune of mull of kintyre:

Far have we travelled and much have we seen
Two wins at Wembley now living the dream
Briers and Morley Ben Westwood on fire
We go to the HJ because we love the wire!!!

(chorus)
We love the wire
With tries rolling in from the wing, my desire
Is always to be here
Cos we love the wire!!!

Reckon that could sound pretty good with a few thousand given it some!

Second best suggestion today after the Dangermouse one...
